Journal Article
Spinel-type lithium cobalt oxide as a bifunctional electrocatalyst for the oxygen evolution and oxygen reduction reactions
2014
Overview
Development of efficient, affordable electrocatalysts for the oxygen evolution reaction and the oxygen reduction reaction is critical for rechargeable metal-air batteries. Here we present lithium cobalt oxide, synthesized at 400 °C (designated as LT-LiCoO
2
) that adopts a lithiated spinel structure, as an inexpensive, efficient electrocatalyst for the oxygen evolution reaction. The catalytic activity of LT-LiCoO
2
is higher than that of both spinel cobalt oxide and layered lithium cobalt oxide synthesized at 800 °C (designated as HT-LiCoO
2
) for the oxygen evolution reaction. Although LT-LiCoO
2
exhibits poor activity for the oxygen reduction reaction, the chemically delithiated LT-Li
1−x
CoO
2
samples exhibit a combination of high oxygen reduction reaction and oxygen evolution reaction activities, making the spinel-type LT-Li

CoO

a potential bifunctional electrocatalyst for rechargeable metal-air batteries. The high activities of these delithiated compositions are attributed to the Co

The development of electrocatalysts for oxygen evolution and reduction is critical for rechargeable metal-air battery applications. Here, the authors synthesize and evaluate a delithiated spinel-type lithium cobalt oxide that exhibits promising performance for both processes.
